The Flues action bar is frequently cited as being weak, thin-walled, too much material plowed out to make room for the gadgetry, not enuf beam section in the water table. Replaced by the much sturdier NID. I've seen too many woozy-loose field-grade NIDs to think this is absolutely the case but haven't seen either Flues or NID with a cracked bar. Question: Does the bar on the Flues SBT share the deficient engineering with that of the doublegun. What got me wondering is the filing of the root of the angle between water table and breech wall on the SBT to an absolute sharp corner (no radius). Everyone with the slightest experience of bending fatigue recognizes this as a stress riser, both today and in the heyday of the double. In fact, the Flues doubles don't have the sharp corner. Anything suspect about the trapguns? I'm using 7800psi, 1 oz. reloads in the one I recently purchased. Too much of a looker (the gun not me) to take chances.
